COMBINED SHOVELING Application filed .Tune 5;

To all whom t may concern.' Y

Be it known that I, ERNEST T. KELL, a citizenrof the United States, anda resident of Benton, in the county of Franklin and' State of Illinois,have invented a new and useful Improvement in Combined Shoveling vandLoading Devices, of 4which the following is a full, clear, and exactdescription. My invention relates to improvements 1n combined shoveliiigand loading devices, and

it consistsV in the combinations, constructions, and arrangements hereindescribed and claimed. l

a frame 1 on which is 'mounted'a power source 2, and a secondpower'source 3. The motor 2 is connected by nism 4 anda chain 4C with a4caterpillar a reversing mecha-v truck 5. From this construction it willbe observed that the frame 1 may bemoved vforwardly `o r backwardly Vbymerely actuat# rear of the device is supported bywheels 7.

A bucket carrying i roller chains 8 and buckets 9 is disposed in thefront of the frame 1 (see Figures 1 and 3). The chains 8 are disposedaround sprockets 9 and 10, and pivotally support the buckets 9therebetween. The sprocket 10 isr secured to a shaft 11 which in turn isdriven by a belt connection 12 from the motor 3. As shown in Figure 1,the motor ing a lever 6 so as to operatively engageV the motor 2 withthe endless tread 5. rIhe means comprisingv 3 is preferably of theelectric type, although it may be of any other type desired. Asheretofore stated, the buckets 9 are pivotally carried by the chains 8by means of trunnions 13 which extend transversely from the buckets 9 atthe vertices thereof. The

buckets in reality form triangular-shaped conveyors. As clearly shown inFigure 4c,

- the front edge Vof the bucket 9 is serrated as at 14C so as to morereadily scoop up fthe coal which has already been blasted; YThe side 15of the bucket has laterallygeXtending ears.16 which are adapted toengage with the lugs '1P/these lugsbeing parts of the chain 8. Y

Guide vmembers 18 are carried by the frame 1 and support the buckets and'chains during a portion of their trip. A second Vpair of guide members19 are disposed-between the sprockets 9 and 10 andare adapted to supportthe ears 16 after the buckets have been emptied. It will be notedfro'mFigure .3 that thevbuckets moving toward the end of the frame 1 havetheir laterally extending projections 2O caught in grooves 21, whereby.the front end of thebucket is f kept do-wn and forcedv into engagementwit-h the pile of coal as the back portion is swung up and around thesprocket 9. As soon as the sprocket 9 starts to carry the bucket 9toward the guideways 18, theprojections 2O have been pushed forwardly soas to clear the guideways 21, and the lugs 17 have engaged with the ears16 of the bucket so as to lift the bucket into the position shown inFigure 3 of the drawings. The Weight of the coal which was formerlycarried by the ggg side 22 of the bucket is now carried by the side 15,this weight in turn being supported by the guideways 18. A furthermovement of the bucket carries it over the sprocket 10, the lugs 17tipping the bucket so as to empty the coal therefrom onto a conveyorbelt 23. A shield 2A prevents the coal from entering the compartmentwhich contains the motors 2 and 3. It will also be apparent that thebucket which has just previously been dumped, forms a shield for thecoal which is being dumped by the succeeding bucket, thereby preventingthe coal from spilling over the end of the conveyor 23. The conveyor 23carries the coal to any loading point, such as a coal car or a coal pile(not shown). rlhe conveyor 23 forms no part of my invention, except inso far as it cooperates with the parts hereinbefore described. Theconveyor is actuated by any means, such as by a motor (not shown). IThebuckets in rounding the sprocket 1() have their vears 16 engaged by theguideways 19 so as to swing the bucket into the desired position. As thebucket moves on, the side 22 engages with the floor 2A of the frame 1,this floor being adapted to guide the projections 2O of the bucket intothe gu'ideways 21. 1n case the fioor of the coal pile, which is beingcarried away by means of the bucket 9, is below the floor 24 of theframe 1, the end o-f the door 211 may be lowered. rlhis construction isclearly shown in Fig. 5 of the drawing.

A plate 25 is pivotally secured at 2,6 to

the frame 1 and is adapted to form a contiguous wall with the floor 24.The frame 25 has upwardly extending lugs 2 7 through which bolts 28 aredisposed, these bolts being slidably mounted in slots 29 in the sides ofthe frame 1. lt is obvious from this construction that the bolts 28 maybe loosened so as to permit the plate 25 to drop into the dotted lineposition shown in Figure 5, whereupon the buckets 9 will scoop the coalfrom a lower plane.

In case the coal which has been dynamited is not loose enough so as toreadily fall into the buckets 9, means for breaking up the coal isactuated. ln fact this means is preferably kept in operation during theoperation of the buckets 9. As clearly shown in Fig. 2, the shaft 30which supports the sprockets 9 also supports sprockets 31. rlhesesprockets are mounted on the inside of the frame 1 and adjacent to thewalls of the frame. Sprockets 3A and 35 are carried by the sides of theframe 1 and are substantially in ver tical alinement with respect toeach other. A roller chain 36 is mounted on the sprockets 31, 311, anc35, this roller chain carrying picks 37. The chains 36 are so disposedthat the picks 37 will project beyond the end of the frame 1 when thepicks are passing between the sprockets 34 and 35. As shown in Figure 2,the picks 37 are removably secured to the chains by means of set screws38. lf the coal is not filling the buckets 9 to the desired capacity,the frame 1 may be moved towards the piley of coal by means of theengine 2 and the caterpillar trucks 5 so as to cause the picks 37 togouge into the pile of coal and to break up the pile into smallerpieces, whereupon the coal will readily fill the buckets and be carriedaway by the conveyor 23.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. As heretofore stated, whenit is desired to remove a pile of coa-l which has previously beendynamited, the tractor is moved towards the desired pile by means of themotor 2. As soon as the tractor has reached the pile, the bucketconveying mechanism may be actuated, and the coal breaking mechanismalso actuated, whereby the coal from the pile will be carried to theconveyor 23 and from thence to the desired location. The buckets 9 areheld in a horizontal position while they are being filled and are alsomoved toward the pile of coal while they are being filled in the mannerherebefore described. lt is obvious that as fast as the buckets carryaway the coal which is disposed adjacent to the forward end of themachine, the machine may be moved towards the pile, whereby the bucketswill again carry away the coal deposited adjacent to the end of themachine.

The device consists of relatively few parts l and is durable andeficient for the purpose intended.
